a rim for mounting a tire on theregular wheel rim, that may. be circumferentially contractedfor the receptionof a tire which may then be expanded to expand thetire to facilitate in transferring it to the wheel rim of the vehicle.

Further objects and purposes. of the invention will appear'as the description proceeds.

throughout which like reference numerals designate like partse Thepnumeral 1 designates the right half or semi-circle, and thenumeral Qthe left semi-circle, ofa circular, mounting 'rim 3, 7 provided on one edge with a rolled flange-4.

The freeends of the member 1 are arranged to overlap the free'ends of the memher- 2, and are providedwith tongues 5,

which project a distance out beyond. the

ends'and engage loops 6 rigidly secured to the member 2 adjacent the free ends thereof.

On the inner'side of the member 1, intermediate the ends thereof, is rigidly secured a bracket 7, which projects inwardly in a 7 direction of the axis of the rim. v The free end of the bracketis slotted, forming thereby .apairof laterally spaced'apart arms 7 and 7 Said arms provided with a plu-.: rality of openings 8. The openings onone of said arms disposed in axial alinement withv the openings 'inithe opposite arm.

. In one of the openings Sof the'a'rm 7 is disposed a pivot pin 9,.which pin also projects through the opening. in the arm '7" registering with the aforesaid opening.

1O designates a bracket rigidly secured to the innerside ofthe member 2 approximately' equi-distant from its ends, having pivot-pin 11 which 'pivotally supports, intermediate its ends, one end of a connecting;

rod-12'. "The opposite end of said connecting rodis forked and supports a pin 13, which pivotally ing lever supports one end of an operate 14, which is fulcrumed intermediate its ends upon the. pivot pin 9.

The arrangement of said brackets and levers being such that by rotating the lever 14 in the proper direction upon the pin 9 it will cause its inner or pivoted end to move to draw the connecting rod in a direction toward the bracket 7, which will cause therim 3 to contract and the ends of the members 1 and 2 to slide alongside of each other,.and

the tongues 5 to slide through the loops 6.

When it is desired to contract the rim to a greater extent than the operation of the lever 141 normally permits, then the pivot pin 9 may be removed and disposed in other openings in the arms 7 and 7 of the bracket 7. I 1

Extending through the sides of the rim 3, and spaced approximately equal distances its free end bifurcated and provided with a apart and extending from a point upwardly adjacent the flange loweredge of the -rim, are disposed four ver- 4 to a point near the tically extending slots 15, the functions of which will hereinafter be fully explained.

Upon the margins of the slots 15 are rigidly'secured brackets 16, which are provided at their free ends with openings 17 supporting pivot pins 18 upon which are pivotally fitted the intermediate sections of levers 19 by-means ofopenings, 20.

Outer portions of'said leversare movable upwardly anddownwardly in the slots when the levers are rotated upon the pins 18.

The outer ends of the levers 19 are flat- V tened and struck upwardly forming bowed h fingers 21 adapted to operatively engage the sides of a tire 22. The convexed portion of the fingers are adapted to engage thelower concaved side of the flange when the levers 19 are rotated as far as they will go in one direction upon the pin 18 (see Fig. 5), and

-are movable in a direction away from said flange when the levers'are rotated 1n the op- I posite dlrection.

In Fig. 550i the drawings 'is shown a tire 22-te'mporarily mounted on the rim 3, pres paratOrylt perm tl o g it on a .Wheelrim 23. p I I i In order to facilitate the operation of the levers 19' in'the removal of the tire 22 from -"chains 25 I 140 able means. -26 designates a plurality of lips struck in- ---wardly from the lower edge of the rim 3 and providea central ringi24tto which the inner ends of saidlevers are connected by means of'chains 25. It is to be understood, how

the rim 3. and mounting it'onthe rim 23, I

- ever,that the'ring24: may be dispensed with,

if so desired, andthe inner ends of the connected togethenby other suitextend at right angles thereto. The functions of said lips are to form offsets adapted to engage one side of the wheel rim 23 to limit the movement of the first. named rim 7 foveror onto said wheel rim. g

It is to be understood that changes in the precise embodiment of the invention as described and illustrated, can be made within the scope of what is claimed without departing from the spirit of the invention.

W'hatI claim as new and desire to secure a by Letters Patent, is:

1. In a tire setter of the character described, a circular rim, means for contracting and expanding the rim, the rim provided with slots extending through from itsinner to its outer periphery, and tire engaging levers having their intermediate portions pivotally supported by the rim and their outer ends movably disposed in said slots;

2. In a tire setter ofthe kind described, a

rim comprising a pair of oppositely disposed semicirclesdisposed in the same plane, the

free ends of one of the semicircles disposed in slidable engagement with the free ends of the other semicircle, the arrangement being such that the rim may be contracted by cansof one of said semicircles proper direction along the 1n the same'plane and operatively movable toward each other for'contracting the rim and movable away from each other for expanding the rim, and alever having one end pivotally connected to an intermediate por- 7 tion of one of said semicircles and an intermediate portionpivotally connected to an intermediate portion of the other of said semicircles, the arrangement being such that by moving ,said'lever in one direction it will cause said semicircles to move relative to each other to expand the rim and by moving the lever in the opposite. direction it will cause the semicircles to move to contract the I rim.

In evidence that the foregoing ismy own,

I hereunto sign my name this 15th day of April, 1920.
